Genes affected

ATM (HGNC:795): (ATM serine/threonine kinase) The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder. [provided by RefSeq, Aug 2010]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.E2374D variant (also known as c.7122A>C), located in coding exon 48 of the ATM gene, results from an A to C substitution at nucleotide position 7122. The glutamic acid at codon 2374 is replaced by aspartic acid, an amino acid with highly similar properties. This alteration has been previously reported in at least one subject in a study of 13087 breast cancer cases and 5488 control individuals in the UK as well as in an individual from a North American cohort of individuals with early-onset colon cancer (Decker B et al. J Med Genet, 2017 11;54:732-741; Pearlman R et al. JAMA Oncol, 2017 Apr;3:464-471). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This missense variant replaces glutamic acid with aspartic acid at codon 2374 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with Lynch syndromeâ€šÃ„Ã¬associated cancer and/or polyps (PMID: 25980754). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Variant summary: ATM c.7122A>C (p.Glu2374Asp) results in a conservative amino acid change located in the PIK-related kinase domain (IPR014009) of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant was absent in 251430 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.7122A>C has been reported in the literature as a VUS in settings of multigene panel testing in individuals undergoing testing for Lynch syndrome (example, Yurgelun_2015). These report(s) do not provide unequivocal conclusions about association of the variant with Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces glutamic acid, which is acidic and polar, with aspartic acid, which is acidic and polar, at codon 2374 of the ATM protein (p.Glu2374Asp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Lynch syndrome or pancreatic cancer (PMID: 25980754, 35047863). ClinVar contains an entry for this variant (Variation ID: 181887). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ATM protein function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
